CHARLES A. NELSON, OE UTICA, NEW YORK, ASSIGNOR TO SAVAGE ARMS COMPANY, 0F TICA, NEW YORK, A CORPORATION OF NEW YORK.

FIREARIVI.

To all whomz't may concern Be it known that I, CHARLES A. NELSON, a citizen of the United States, residing at Utica, in the county of Oneida and State of N ew York, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention consists, first, in a novel combination of instrumentalities whereby the ring-mechanism, normally disposed to require such degree of movement of the releasing means for its firing member as is consistent with safety in ordinary handling of the arm, may be quickly and readily7 set to such a condition as to require any less degree of movement of its releasing means; and, second, in such a novel form and construction of certain parts of a gun of the type of that illustrated in the patent to A. W. Savage, No. 491138, for instance, that the operator can readily detect the presence or absence of a cartridge in the breech.

In the accompanying drawings, Figure 1 is a side elevation of Vso much of an arm of the type shown in the aforesaid patent to Savage as is necessary to illustrate'the first part of my invention; Fig. 2 shows the parts immediately involved in the first part of my invention on a larger scale and also in side elevation; Fig. 3 is a sectional view on line .o0-m of Fig. 2; Figs. 4, 5 and 6 are rear, side and front elevations, respectively, of the scar-shifting lever; Fig. 7 is a left side elevation of the arm; Fig; 8 la plan of so much thereof as concerns the second part of my invention; Figs. 9 and 10 are horizontal and vertical sectional views `of so much of the arm as appears in Fig. 8; and, Fig. l1 is a. front elevation of the cartridge-retainer.

rlhe barrel a, stock Z), frame c, breech-bolt Z containing the spring-pressed firing pin e and movable under the iniiuence of the vcontrolling lever f to perform the functions assigned thereto in said patent, the Sear g pivoted to move in the frame in a vertical plane and having a stop-face g to engage the firing-pins stop-face e arranged substantially perpendicular to the path of travelof the firing-pin, and the trigger z pivoted in the frame and coupled with the sear by the slot and pin connection i so as to move in unison with said sear and having a spring '7' holding it retracted and normally elevating the sear, are or may be all substantially the same as in the Savage patent referred to.

Specification of Letters Patent.

Application filed October 15, 1912.

Patented Nov. 3, 1914i. Serial No. 725,946.

On the pin 7c, affording the fulcrum for the trigger, is fulcrumed the aforesaid searslnfting or setting` lever, designated Z in the drawings. piece having its major or body portion forward of its fulcrum. At its forward eX- tremity and at the upper part thereof projects forwardly a toe or lug m which overhangs and is adapted to bear downwardly against the chamfered face n formed at the rear end of the sear.- Projecting downwardly from the forward portion of the lever is a stirrup 0 whose extremity is somewhat enlarged and bent o laterally-at a right angle to form a thumb-piece or handle p, being preferably milled on its upper surface. rlhe lever is housed in a groove p formed in the rearwardly projecting parte of the frame on the side of the trigger which is toward the observer in Figs. l, 2l and 3; in coincidence with its stirrup an opening 1", entering to said groove, is cut in the frame, the stirrup being arranged to play in this opening and, by being bent outwardly as shown in Figs. l and 6, having` its outer face flush with the outer surface of the adjoining part of the frame a. On the bottom of said groove, under the lever, is seated a spiral spring s upon which the forward portion `of the lever rests. Forward of the spring a vertical set screw t is tapped into the frame, the same projecting up into the aforesaid groove beneath the lever.

The normal position which the sear and firing pin assume when the gun is cocked being that shown by fulldines in Fig. 2, in which position their stop-faces overlap to the extent shown in said ligure it requires relatively appreciable movement of the trigger to move the sear sufficiently to release the firing pin. If the operator has occasion to require less movement of the sear to clear it from the firing-pin he shifts lever Z downwardly, by pressing on the handle j) of said lever, until it brings against the set screw t. In so doing, the sear is depressed and the trigger' shifted to a corresponding extent, the parts being held in the new position by the frictional action of the stop-face of the firing-pin on that of the scar under the influence of the spring of the firing pin. The degree to which the sear may thus be shifted downwardly may be adjusted to suit the operator by turning the set-screw t and thereby altering the limit it affords the This is a generally flat metallic lever in its downward movement. After firing and re-cocking the parts assume the normal position (full lines, Fig. 2).

As in the said Savage patent, the cartridges are retained in the magazine u of the arm by the cartridge retainer 'u in the form of a lever pivoted at its lower end within the magazine and having a forwardly projecting arm w (Fig. 9). When a cartridge is inserted at the opening (Fig. IO) into the magazine, or when the breech bolt is in the closed position, the arm w recedes into a recess y toward the observer in Fig. 9. I utilize the cartridge retainer in the present instance as a means for detecting the presence or absence of a cartridge A in the breech, thus: I extend the saine forward and provide thereon a toe e which so nearly y reaches the rear end of the barrel that when a cartridge is in position in the barrel the tce will bear against the side of the cartridge rim. lVith the retainer so engaging the cartridge rim it is held outwardly somewhat farther than it is held by the breechbolt if there is no cartridge in the breech, the additional extent of movement allowed the retainerbeiiig afforded bydeepening the recess y, which is farther extended forward to the rear end of the barrel, as at y (Fig. l0

2 is an `orifice entering the recess g/-y through the side of the magazine from the exterior, and 3 is a lug or button formed on the retainer and coinciding with this orifice, `being of such length that in the normal position of the retainer (that is, with the breech closed and no cartridge therein) the button-will lie more or less iush with the outer surface of the magazine5vbut with a cartridge present in the breech the button will be held'outwardly to such an extent that the fact that it projects may be readily detected by the operators thumb.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, with the frame, a firing member,v a pivoted sear having a stop-face to be engaged by and retain cocked posie tion the iiringmember, the sear being pivot-r ally movable in wiping contact `with said member to clear and thereby releasethe firing member, a trigger for moving the sear on its pivotto the position to clear the firing member, and means to move the Sear on its pivot a distance short of that ynecessary to release the firing member including a@ i and movable in the frame ony an axis parallel with the guns axis into and out ofobstructing vrelation yto `said opening' and having thereon a forward extension projecting into contiguity to the barrel and adapted to bearl against` one yside ofthe cartridge therein, said frame having an opening' exposing-a part of the retainer, substantially asl described.

3. In combination, the gun frame having a magazine and an opening leading thereto, i Y

the barrel having its rearend adj oining Ithe magazine, and a cartridge-retainer housed I and movablein the frame inwardly and out' wardly on an axis parallel with the gunxs axis into and out ofobstructing relation to said opening and having thereon a forward v extension projecting into contiguityto the i barrel and adapted to bear against one side of the cartridge therein and also having a.

projection on its outer side, said frame having an opening coinciding with and exposing said proiection, substantially as described.

In testimony whereof I aiix my signaturey in presence of two witnesses.
